beautiful workmanship

man I am so happy that I purchased the 3" gxp downpipe and 2.5" full exhaust. the workmanship on the welds is absolutely beautiful and the exhaust fit like a glove. looks and sounds absolutely wonderful and I know from the quality of the materials this exhaust is gonna last a long time compared to any exhaust I would've spent more money on at a muffler shop for lower quality materials. thanks so much ZZP for your high quality workmanship me and my car both love you for it! very very satisfied customer!

Instead of throwing money at a muffler shop to install some cheap exhaust on your ride that will rust out in a few years, invest in a ZZP stainless exhaust and it will last a very long time. Had some fun installing this stainless catback system. Installed stainless from the manifolds back with the ceramic coated cross over pipe and the 2.5 inch 400 cell cat down pipe. The car loves me for it! The craftsmanship of this catback system and the down pipe is superb! I looked at the welds on the down pipe and said "Damn!, that's nice!". Right on ZZP.
